## Abstract

Casting facility includes a pouring machine for pouring molten metal in a ladle into a mold molded by a molding machine and conveyed to a pouring site, and the pouring machine includes a plan acquisition unit configured to acquire a planned temperature range of the molten metal for the mold, a temperature sensor configured to detect a temperature of a pouring flow during pouring of the molten metal into the mold, and a temperature determination unit configured to determine whether or not the temperature of the pouring flow is within the planned temperature range, and the pouring machine stops the pouring of the molten metal into the mold when it is determined that the temperature of the pouring flow is not within the planned temperature range.

## Claims

### Claim 1

Casting facility comprising a pouring machine for pouring molten metal in a ladle into a mold molded by a molding machine and conveyed to a pouring site,
wherein the pouring machine comprises:
a plan acquisition unit configured to acquire a planned temperature range of the molten metal for the mold conveyed to a pouring position from the molding machine;
a temperature sensor configured to detect a temperature of a pouring flow during pouring of the molten metal into the mold conveyed to the pouring position; and
a temperature determination unit configured to determine whether or not the temperature of the pouring flow detected by the temperature sensor is within the planned temperature range acquired by the plan acquisition unit, and
wherein the pouring machine stops the pouring of the molten metal into the mold when it is determined by the temperature determination unit that the temperature of the pouring flow is not within the planned temperature range.

### Claim 2 (depends on 1)

The casting facility according to claim 1, further comprising a conveying device configured to convey the ladle to the pouring machine,
wherein the plan acquisition unit further acquires a planned material number of the mold conveyed to the pouring position, from the molding machine,
wherein the pouring machine further comprises:
a material acquisition unit configured to acquire a material number for identifying a material of the molten metal in the ladle from the conveying device; and
a material determination unit configured to determine whether or not the planned material number acquired by the plan acquisition unit and the material number acquired by the material acquisition unit match each other, and
wherein the pouring machine stops the pouring of the molten metal into the mold when it is determined by the material determination unit that the planned material number and the material number do not match each other.

### Claim 3 (depends on 1)

The casting facility according to claim 1, wherein based on information acquired from the molding machine, the plan acquisition unit further acquires a ladle tilting pattern for pouring the molten metal into the mold conveyed to the pouring position, and a time change of a weight of the ladle when the molten metal is poured according to the ladle tilting pattern,
wherein the pouring machine refers to a storage unit in which a correction value for correcting a tilting operation of the ladle is stored, and pours the molten metal into the mold conveyed to the pouring position based on the ladle tilting pattern acquired by the plan acquisition unit and the correction value stored in the storage unit,
wherein the pouring machine further comprises:
a load cell configured to measure the weight of the ladle during pouring of the molten metal into the mold conveyed to the pouring position; and
an update unit configured to update the correction value stored in the storage unit so that a deviation between the weight of the ladle measured by the load cell and the weight of the ladle at a time of measurement by the load cell acquired by the plan acquisition unit decreases.

### Claim 4 (depends on 2)

The casting facility according to claim 2, wherein based on information acquired from the molding machine, the plan acquisition unit further acquires a ladle tilting pattern for pouring the molten metal into the mold conveyed to the pouring position, and a time change of a weight of the ladle when the molten metal is poured according to the ladle tilting pattern,
wherein the pouring machine refers to a storage unit in which a correction value for correcting a tilting operation of the ladle is stored, and pours the molten metal into the mold conveyed to the pouring position based on the ladle tilting pattern acquired by the plan acquisition unit and the correction value stored in the storage unit,
wherein the pouring machine further comprises:
a load cell configured to measure the weight of the ladle during pouring of the molten metal into the mold conveyed to the pouring position; and
an update unit configured to update the correction value stored in the storage unit so that a deviation between the weight of the ladle measured by the load cell and the weight of the ladle at a time of measurement by the load cell acquired by the plan acquisition unit decreases.
